TypeError: ufunc 'add' output (typecode 'O') could not be coerced to provided output parameter (typecode 'd') according to the casting rule ''same_kind''

Dear cSPARC community,

Had anyone encountered the appended error when trying to run a refinement using an imported reference structure? Have you managed to understand what it means and how to fix it?

Thanks for your help!

Cheers,
Kyle
